How do I calculate sales tax?

Multiply the taxable amount by the rate. At 8.25%, tax on $100.00 is $100.00 × 0.0825 = $8.25, so the total is $108.25.

How do I take sales tax out of a total (reverse sales tax)?

Divide the total by 1 plus the rate. For a $108.25 total at 8.25%: $108.25 ÷ 1.0825 = $100.00 before tax, so the tax was $8.25.

Which states have no sales tax?

Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Alaska lets local governments charge one, averaging about 1.82%.

Are these the exact rates for my city?

No. The state rate is exact, but the local figure is a population-weighted average from the Tax Foundation (as of July 1, 2026). Local rates vary by city, county and district, so use "My exact rate" with the rate from your receipt or state revenue department when you need to be precise.

Where do the rates come from?

State and average local rates come from the Tax Foundation, "2026 Sales Tax Rates, Midyear Update" (rates as of July 1, 2026). Tax rules on what is taxable (food, clothing, services) also differ by state.

Are my files or text uploaded anywhere?

No. This tool runs entirely in your browser using JavaScript. Nothing you enter or open is sent to our servers or stored by us.
